This graph also tells us that Witcher 3 had higher sales in 2017 than in 2016 .Kudos.
Also, lets assume for all three years PC was all digital for Witcher 3 (i know thats not the total case, but still)
If we go by that scenario, then in 2015, people on console bought 100% physical. In 2016, 71.4% bought physical, and in 2017, 52% bought physical.
And a small number of players probably bought the physical PC version, so those percentages are a bit lower in reality. This goes to show that Digital is taking over.
Another example of this shift is assassins creed. Syndicate sold 12% of its copies digital, while Origins sold 35% digital.
Bet with Intrinsic:
The Switch will outsell 3DS (based on VGchartz numbers), according to me, while Intrinsic thinks the opposite will hold true. One month avatar control for the loser's avatar.
